Ensemble Streamflow Prediction (ESP) provides the means for statistical post-processing of the forecasts and estimating the inherent uncertainties. On the other hand large scale climate variables provide valuable information for hydrologic predictions. In this study we propose a post-processing procedure that assigns weights to streamflow ensemble members using these large...
The present increasing need for the development of empirical hypotheses that explain the decisionmakers' behavior towards risk is to provide an understanding of the framework within which an industry operates. Such hypotheses could facilitate the implementation of policies designed to solve problems identified within an industry and could also provide...
This dissertation investigates by means of computer simulation the potential of a
Band Variable-Inertia Flywheel (BVIF) to store energy for an urban transit bus.
Replacing both a fixed-inertia flywheel (FIF) and a continuously variable transmission
(CVT), the Band Variable-Inertia Flywheel is capable of accelerating a vehicle
from rest to a...
One important aspect related to the management of water resources under future climate variation is the occurrence of extreme precipitation events. In order to prepare for extreme events, namely floods and droughts, it is important to understand how future climate variability will influence the occurrence of such events. Recent advancements...
Sampling theorems provide exact interpolation formulas for bandlimited
functions. They play a fundamental role in signal processing. A function is called
bandlimited if its Fourier transform vanishes outside a compact set. A generalized
sampling theorem in the framework of locally compact Abelian groups is presented.
Sampling sets are finite unions...
This research explores several novel approaches to improve visualization and segmentation
of point clouds acquired with 3D laser scanning. 3D laser scanning is used
in a wide variety of applications including surveying and mapping, transportation asset
management, facilities management, building information modeling, crime scene investigations,
cultural heritage and geologic instigations....
In wireless sensor networks (WSNs) nodes are battery powered. Therefore, the available
energy resources of sensor nodes should be managed efficiently in order to increase
the network lifetime. As a result, researchers have proposed routing schemes in order to
maximize network lifetime. Even though these schemes increase the network lifetime,...
Wildland fire refers to an unpredictable and uncontrollable fire that happens in wildland areas. Regardless of the beneficial impacts of wildland fires on ecosystems, the destructive impacts of wildfires on air quality, economy, public health, etc. are considerable. An essential goal in the fire community is that the wildland fires...
The paper addresses the problem of communication between co-existing DBMSs. Specifically, two data models--that is, the Network and Relationals models--have been analyzed using their respective implementations CODASYL DBTG and System R.
Feasibility of communication is discussed and mapping mechanisms are suggested between the two DBMSs at the following levels:
-...
